Win32_PageFileUsage perl sample code

The foundations for Manageability in Windows is Windows Management Instrumentation (WMI; formerly WBEM) and WMI extensions for Windows Driver Model (WDM).

ActiveXperts Network Monitor provides the ability to build monitor check routines based on WMI. ActiveXperts has collected more than a hundred WMI samples. You can use these samples as a base for new check routines you can write yourself. The Win32_PageFileUsage WMI class can be used in ActiveXperts Network Monitor to monitor your servers.

Description

The Win32_PageFileUsage WMI class represents the file used for handling virtual memory file swapping on a Win32 system. Information contained within objects instantiated from this class specify the run-time state of the page file.

Sample Code

use strict;
use Win32::OLE('in');

use constant wbemFlagReturnImmediately => 0x10;
use constant wbemFlagForwardOnly => 0x20;

my @computers = ("\localhost");
foreach my $computer (@computers) {
   print "\n";
   print "==========================================\n";
   print "Computer: $computer\n";
   print "==========================================\n";

   my $objWMIService = Win32::OLE->GetObject("winmgmts:\\\\$computer\\root\\CIMV2") or die "WMI connection failed.\n";
   my $colItems = $objWMIService->ExecQuery("SELECT * FROM Win32_PageFileUsage", "WQL",
                  wbemFlagReturnImmediately | wbemFlagForwardOnly);

   foreach my $objItem (in $colItems) {
      print "AllocatedBaseSize: $objItem->{AllocatedBaseSize}\n";
      print "Caption: $objItem->{Caption}\n";
      print "CurrentUsage: $objItem->{CurrentUsage}\n";
      print "Description: $objItem->{Description}\n";
      print "InstallDate: $objItem->{InstallDate}\n";
